为深入了解湖南烤烟总糖含量区域特征,对湖南主产烟区烤烟的总糖含量进行了测定和统计分析。结果表明:湖南主产烟区不同部位的总糖含量是下部>中部>上部,部位间存在极显著差异,主栽的品种之间总糖含量在统计学上不存在显著差异,但年度之间总糖含量存在极显著的差异。湖南烤烟上、中部烟叶总糖含量在地区间、生态区域间差异显著,但下部烟叶差异不显著。聚类分析将湖南烤烟总糖含量大体可分为低总糖区、上中部烟叶高总糖区、下部烟叶高总糖区三大类型。湖南烤烟总糖含量不同部位的空间分布存在一定差异。
In order to further understand the regional characteristics of total sugar content in flue-cured tobacco in Hunan, the total sugar content of flue-cured tobacco in main producing areas in Hunan Province was determined and statistically analyzed. The results showed that the total sugar content in different parts of the main tobacco producing areas in Hunan Province was lower> middle> upper part, with significant differences among the parts. There was no significant difference in the total sugar content between the main cultivars, but between the years Total sugar content there is a very significant difference. In Hunan flue-cured tobacco, the total sugar content in the middle part of the tobacco leaves was significantly different between the regions, but the difference in the lower part of the tobacco leaves was not significant. Cluster analysis of the total sugar content of Hunan flue-cured tobacco can be divided into low total sugar area, the upper middle of the tobacco high total sugar area, the lower tobacco leaves of the three types of high total sugar. There is a certain difference in the spatial distribution of different parts of total sugar content in Hunan flue-cured tobacco.
